Test Tube Stand, Aluminium/Stainless Steel, 3 Tier

Quick Answer: The Test Tube Stand, Aluminium/Stainless Steel, 3 Tier is a 3 tier test tube stand built from three metal plates: two drilled plates that hold the tubes upright and a solid base they rest on. The listing photograph shows a bright, box-like rack with several rows of holes; the title offers it in aluminium or stainless steel.

Why Three Tiers Hold Tubes Straighter

A single drilled board holds a tube at one height only, so a tall tube can lean in its hole. In a three-tier rack each tube passes through two holes, one in the top plate and one in the middle plate, before resting on the base. Two guide points in line keep it vertical, which matters for tall culture tubes, for reading liquid levels across a series, and for uncapped tubes that must not tip.

Being metal, the stand can go where the tubes go: into a hot air oven or autoclave with a load of clean tubes, or into a sink for washing. Aluminium is the lighter choice; stainless steel is heavier and better suited to strong detergents and disinfectants, which attack aluminium.

Hole diameter and the number of rows are not given in the title, so match the stand to your tube size. For washing and sterilising tubes in bulk without fixed positions, the perforated test tube basket is the companion item; for mixed tube sizes, the test tube holder rack in the glassware range is an alternative.

Applications

• Holding tubes of culture medium upright through autoclaving and cooling
• Serial dilution series in microbiology and biochemistry practicals
• Keeping a standard colour series in order for visual comparison
• Incubating enzyme or food-test tubes in a water bath

Specifications

Care & Handling

• Clean an aluminium 3 tier test tube stand with neutral detergent; alkaline cleaners dull and pit it.
• Rinse and dry after use, and do not leave chloride solutions standing on stainless steel.
• Load tubes of similar height so the rack is not top-heavy on one side.

Why Choose LabEquip

Microbiology, pathology and biotechnology teaching labs use metal tiered stands because they survive repeated sterilisation. LabEquip lists this rack in both metals in General Lab Products.

Frequently Asked Questions

What is the advantage of a three-tier stand?

Each tube passes through holes in two plates before resting on the base, so it is held at two heights and stays vertical. Single-tier racks let tall tubes lean.

Can it go in an autoclave?

Both aluminium and stainless steel tolerate normal autoclave temperatures, so the stand can be sterilised with its tubes. Let it cool before handling.

Aluminium or stainless steel: which should I choose?

Aluminium is lighter and conducts heat quickly, but alkaline detergents attack it. Stainless steel is heavier and more tolerant of detergents and disinfectants.

Can I use it in a water bath?

Metal racks are commonly used in water baths. Keep the water level below the top plate and make sure the rack sits steadily on the bath floor.

Will it hold different tube sizes?

The holes suit one diameter range. Very narrow tubes lean in large holes and wide tubes will not fit, so match the stand to the tubes you use most.

How do I carry a loaded stand safely?

Fill it evenly and carry it level with both hands. For moves between rooms, set the stand in a tray so a tipped tube cannot spill onto the floor.
